- the selected wild symbols are locked in place on the second enhanced array 104 b while the second-enhanced-array reels 110 a - 110 e are spun.
- a game outcome is then determined based on the locked wild symbols and on the randomly selected symbols displayed on the remaining positions of the second enhanced array 104 b.
- the illustrated “reduced symbol set” enhancement feature 116 c ( FIG. 4A ) is applied to the third enhanced array 104 c by the gaming system after the third enhanced array 104 c is unlocked.
- the “reduced symbol set” enhancement feature 116 c includes a plurality of symbols arranged on the plurality of the third-enhanced-array reels 112 a - 112 e of the third enhanced array 104 c .
- the set of symbols on the third-enhanced-array reels 112 a - 112 e includes symbols used on the main array 102 , but excludes the lowest paying symbols in that set.
- the number of symbols excluded from the third-enhanced-array reels 112 a - 112 e may be varied to achieve a desired result.
- the set of excluded symbols can be a predetermined set or can be randomly determined by the gaming system during play of the wagering game.
- FIG. 5 illustrates a schematic depiction of one algorithm that corresponds to at least some instructions that can be executed by the CPU 30 and/or external systems 48 to perform the above described functions associated with the disclosed concepts.
- the exemplary algorithm 200 includes receiving a wager, at step 202 , from a player to initiate a wagering game. The wager is placed or otherwise confirmed, for example, using a bill validator 22 , coin acceptor, information reader 24 , or other input device.
- a main array and enhanced arrays are displayed at step 204 (e.g., the main array 102 and enhanced arrays 104 a - 104 c of FIG. 4A ). It is contemplated that the main array and the enhanced arrays can also be displayed prior to initiation of the wagering game.
- the main array includes a plurality of symbol-bearing reels that are spun and evaluated at step 206 (e.g., the main-array reels 106 a - 106 e of FIGS. 4A-4C ). It is determined, at decision box 208 , whether a triggering condition has occurred that enables play of any enhanced arrays (e.g., as shown in FIG. 4B , the first-enhanced-array trigger symbol 114 a being displayed on the rightmost main-array reel 106 e allows play of the first enhanced array 104 a ).
- a triggering condition e.g., as shown in FIG. 4B , the first-enhanced-array trigger symbol 114 a being displayed on the rightmost main-array reel 106 e allows play of the first enhanced array 104 a ).
- an award determination is made at step 212 to evaluate whether the main array resulted in an award to the player.
- at least one enhanced array associated with the triggering condition is unlocked and the symbol-bearing reels on the unlocked enhanced array are spun and evaluated at step 210 .
- the unlocked enhanced array includes a plurality of symbol-bearing reels (e.g., the first-enhanced-array reels 108 a - 108 e shown in FIG. 4B ). It is contemplated that multiple triggering conditions may occur simultaneously and that either all or fewer than all enhanced arrays associated with the triggering conditions may be played. It is further contemplated that multiple enhanced arrays may be associated with a single trigger symbol (e.g., the multiple-enhanced-array trigger symbol 114 d shown in FIG. 4C ).
- an award determination is made at step 212 to evaluate whether the main array, enhanced array, both, or neither resulted in an award to the player. These awards are based on, for example, combinations of symbols displayed on the main array and symbols displayed on any unlocked array. The player is provided with any determined awards at step 214 and play of the wagering game may continue.
- play of the unlocked enhanced arrays can unlock other of the enhanced arrays or cause the main array to respin.
- play of the first enhanced array 104 a can result in displaying a second-enhanced-array trigger symbol 114 b that unlocks the second enhanced array 104 b .
- play of the first enhanced array 104 a can result in a respin symbol that causes the main array 102 to respin one or more times.
- the respinning of the main array 102 can potentially unlock other enhanced arrays, for example, a third-enhanced-array trigger symbol 114 c unlocks the third enhanced array 104 c.
- the number of enhanced-array trigger symbols 114 a - 114 d increases if a free-spin bonus game is triggered on the main array 102 .
- the plurality of main-array reels 106 a - 106 e includes only three enhanced-array trigger symbols 114 a - 114 c during the base game, each of the enhanced-array trigger symbols 114 a - 114 c being able to unlock a single and distinct one of the enhanced arrays 104 a - 104 c .
- the multiple-enhanced-array trigger symbol 114 d is added to the plurality of symbol positions on at least one of the main-array reels 106 a - 106 e .
- the multiple-enhanced-array trigger symbol 114 d is able to unlock all three enhanced arrays 104 a - 104 c simultaneously.
- all of the single, enhanced-array trigger symbols 114 a - 114 c convert to multiple-enhanced-array trigger symbols 114 d.
- the number of enhanced-array trigger symbols 114 a - 114 d does not change when the free-spin bonus is initiated.
- an enhanced array that becomes unlocked due to a triggering condition remains unlocked and is spun and evaluated for the remainder of the free spins. For example, if the free-spin bonus has ten free spins and the first enhanced array 104 a is unlocked during the third free spin, the first enhanced array 104 a remains unlocked and is spun and evaluated for each of the remaining seven spins (in addition to the third spin).
- a single-symbol trigger may be implemented on any of the main-array reels 106 a - 106 e .
- a combination of symbols or a specific placement of symbols may be required to unlock the enhanced arrays. This requirement can include a trigger with three symbols where all three symbols indicate the enhanced array to be unlocked. For example, in reference to FIG. 4B , two additional first-enhanced-array trigger symbols 114 a would be required to be displayed on any of the main-array reels 106 a - 106 e .
- the three first-enhanced-array trigger symbols 114 a could be required to be located in a specific location or orientation (e.g., all three symbols must be located in a top position on any of the main-array reels 106 a - 106 e of the main array 102 ).
- the three symbols could be different from one another (e.g., one symbol identifies the enhanced array to be unlocked and the other two symbols are generic bonus symbols).

Generally, the popularity of such machines with players is dependent on the likelihood (or perceived likelihood) of winning money at the machine and the intrinsic entertainment value of the machine relative to other available gaming options. Where the available gaming options include a number of competing machines and the expectation of winning at each machine is roughly the same (or believed to be the same), players are likely to be attracted to the most entertaining and exciting machines. Shrewd operators consequently strive to employ the most entertaining and exciting machines, features, and enhancements available because such machines attract frequent play and hence increase profitability to the operator. Therefore, there is a continuing need for gaming machine manufacturers to continuously develop new games and improved gaming enhancements that will attract frequent play through enhanced entertainment value to the player.
- According to one aspect of the present invention, a gaming system for conducting a wagering game includes at least one input device, at least one display device, at least one processor, and at least one memory device.

- Referring to
FIG. 1 , there is shown agaming terminal 10 similar to those used in gaming establishments, such as casinos. With regard to the present invention, thegaming terminal 10 may be any type of gaming terminal and may have varying structures and methods of operation. For example, in some aspects, thegaming terminal 10 is an electromechanical gaming terminal configured to play mechanical slots, whereas in other aspects, the gaming terminal is an electronic gaming terminal configured to play a video casino game, such as slots, keno, poker, blackjack, roulette, craps, etc. Thegaming terminal 10 may take any suitable form, such as floor-standing models as shown, handheld mobile units, bartop models, workstation-type console models, etc. Further, thegaming terminal 10 may be primarily dedicated for use in conducting wagering games, or may include non-dedicated devices, such as mobile phones, personal digital assistants, personal computers, etc. Exemplary types of gaming terminals are disclosed in U.S. Pat. No. 6,517,433 and Patent Application Publication Nos. US2010/0069160 and US2010/0234099, which are incorporated herein by reference in their entireties. - The
gaming terminal 10 illustrated inFIG. 1 comprises acabinet 11 that may house various input devices, output devices, and input/output devices. By way of example, thegaming terminal 10 includes aprimary display area 12, asecondary display area 14, and one ormore audio speakers 16. Theprimary display area 12 or thesecondary display area 14 may be a mechanical-reel display, a video display, or a combination thereof in which a transmissive video display is disposed in front of the mechanical-reel display to portray a video image superimposed upon the mechanical-reel display. The display areas may variously display information associated with wagering games, non-wagering games, community games, progressives, advertisements, services, premium entertainment, text messaging, emails, alerts, announcements, broadcast information, subscription information, etc. appropriate to the particular mode(s) of operation of thegaming terminal 10. Thegaming terminal 10 includes a touch screen(s) 18 mounted over the primary or secondary areas,buttons 20 on a button panel,bill validator 22, information reader/writer(s) 24, and player-accessible port(s) 26 (e.g., audio output jack for headphones, video headset jack, USB port, wireless transmitter/receiver, etc.). It should be understood that numerous other peripheral devices and other elements exist and are readily utilizable in any number of combinations to create various forms of a gaming terminal in accord with the present concepts. - Input devices, such as the
touch screen 18,buttons 20, a mouse, a joystick, a gesture-sensing device, a voice-recognition device, and a virtual input device, accept player input(s) and transform the player input(s) to electronic data signals indicative of the player input(s), which correspond to an enabled feature for such input(s) at a time of activation (e.g., pressing a “Max Bet” button or soft key to indicate a player's desire to place a maximum wager to play the wagering game). The input(s), once transformed into electronic data signals, are output to a CPU for processing. The electronic data signals are selected from a group consisting essentially of an electrical current, an electrical voltage, an electrical charge, an optical signal, an optical element, a magnetic signal, and a magnetic element. - Turning now to
FIG. 2 , there is shown a block diagram of the gaming-terminal architecture. Thegaming terminal 10 includes a central processing unit (CPU) 30 connected to amain memory 32. TheCPU 30 may include any suitable processor(s), such as those made by Intel and AMD. By way of example, theCPU 30 includes a plurality of microprocessors including a master processor, a slave processor, and a secondary or parallel processor.CPU 30, as used herein, comprises any combination of hardware, software, or firmware disposed in or outside of thegaming terminal 10 that is configured to communicate with or control the transfer of data between thegaming terminal 10 and a bus, another computer, processor, device, service, or network. TheCPU 30 comprises one or more controllers or processors and such one or more controllers or processors need not be disposed proximal to one another and may be located in different devices or in different locations. TheCPU 30 is operable to execute all of the various gaming methods and other processes disclosed herein. Themain memory 32 includes awagering game unit 34. In one embodiment, thewagering game unit 34 may present wagering games, such as video poker, video black jack, video slots, video lottery, etc., in whole or part. - The
CPU 30 is also connected to an input/output (I/O)bus 36, which can include any suitable bus technologies, such as an AGTL+frontside bus and a PCI backside bus. The I/O bus 36 is connected tovarious input devices 38,output devices 40, and input/output devices 42 such as those discussed above in connection withFIG. 1 . The I/O bus 36 is also connected tostorage unit 44 andexternal system interface 46, which is connected to external system(s) 48 (e.g., wagering game networks). - The
external system 48 includes, in various aspects, a gaming network, other gaming terminals, a gaming server, a remote controller, communications hardware, or a variety of other interfaced systems or components, in any combination. In yet other aspects, theexternal system 48 may comprise a player's portable electronic device (e.g., cellular phone, electronic wallet, etc.) and theexternal system interface 46 is configured to facilitate wireless communication and data transfer between the portable electronic device and theCPU 30, such as by a near-field communication path operating via magnetic-field induction or a frequency-hopping spread spectrum RF signals (e.g., Bluetooth, etc.). - The
gaming terminal 10 optionally communicates with theexternal system 48 such that the terminal operates as a thin, thick, or intermediate client. In general, a wagering game includes an RNG for generating a random number, game logic for determining the outcome based on the randomly generated number, and game assets (e.g., art, sound, etc.) for presenting the determined outcome to a player in an audio-visual manner. The RNG, game logic, and game assets are contained within the gaming terminal 10 (“thick client” gaming terminal), the external system 48 (“thin client” gaming terminal), or are distributed therebetween in any suitable manner (“intermediate client” gaming terminal). - The
gaming terminal 10 may include additional peripheral devices or more than one of each component shown inFIG. 2 . Any component of the gaming terminal architecture may include hardware, firmware, or tangible machine-readable storage media including instructions for performing the operations described herein. Machine-readable storage media includes any mechanism that stores information and provides the information in a form readable by a machine (e.g., gaming terminal, computer, etc.). For example, machine-readable storage media includes read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory, etc. - Referring now to
FIG. 3 , there is illustrated an image of a basic-game screen 50 adapted to be displayed on theprimary display area 12 or thesecondary display area 14. The basic-game screen 50 portrays a plurality of simulated symbol-bearingreels 52. Alternatively or additionally, the basic-game screen 50 portrays a plurality of mechanical reels or other video or mechanical presentation consistent with the game format and theme. The basic-game screen 50 also advantageously displays one or more game-session credit meters 54 and varioustouch screen buttons 56 adapted to be actuated by a player. A player can operate or interact with the wagering game using these touch screen buttons or other input devices such as thebuttons 20 shown inFIG. 1 . The CPU operate(s) to execute a wagering game program causing theprimary display area 12 or thesecondary display area 14 to display the wagering game. - In response to receiving a wager, the
reels 52 are rotated and stopped to place symbols on the reels in visual association with paylines such aspaylines 58. The wagering game evaluates the displayed array of symbols on the stopped reels and provides immediate awards and bonus features in accordance with a pay table. The pay table may, for example, include “line pays” or “scatter pays.” Line pays occur when a predetermined type and number of symbols appear along an activated payline, typically in a particular order such as left to right, right to left, top to bottom, bottom to top, etc. Scatter pays occur when a predetermined type and number of symbols appear anywhere in the displayed array without regard to position or paylines. Similarly, the wagering game may trigger bonus features based on one or more bonus triggering symbols appearing along an activated payline (i.e., “line trigger”) or anywhere in the displayed array (i.e., “scatter trigger”). The wagering game may also provide mystery awards and features independent of the symbols appearing in the displayed array. - In accord with various methods of conducting a wagering game on a gaming system in accord with the present concepts, the wagering game includes a game sequence in which a player makes a wager and a wagering game outcome is provided or displayed in response to the wager being received or detected. The wagering game outcome is then revealed to the player in due course following initiation of the wagering game. The method comprises the acts of conducting the wagering game using a gaming apparatus, such as the
gaming terminal 10 depicted inFIG. 1 , following receipt of an input from the player to initiate the wagering game. Thegaming terminal 10 then communicates the wagering game outcome to the player via one or more output devices (e.g.,primary display 12 or secondary display 14) through the display of information such as, but not limited to, text, graphics, static images, moving images, etc., or any combination thereof. In accord with the method of conducting the wagering game, the CPU transforms a physical player input, such as a player's pressing of a “Spin Reels” touch key, into an electronic data signal indicative of an instruction relating to the wagering game (e.g., an electronic data signal bearing data on a wager amount). - In the aforementioned method, for each data signal, the CPU (e.g., CPU 30) is configured to process the electronic data signal, to interpret the data signal (e.g., data signals corresponding to a wager input), and to cause further actions associated with the interpretation of the signal in accord with computer instructions relating to such further actions executed by the controller. As one example, the CPU causes the recording of a digital representation of the wager in one or more storage media (e.g., storage unit 44), the CPU, in accord with associated computer instructions, causing the changing of a state of the storage media from a first state to a second state. This change in state is, for example, effected by changing a magnetization pattern on a magnetically coated surface of a magnetic storage media or changing a magnetic state of a ferromagnetic surface of a magneto-optical disc storage media, a change in state of transistors or capacitors in a volatile or a non-volatile semiconductor memory (e.g., DRAM), etc. The noted second state of the data storage media comprises storage in the storage media of data representing the electronic data signal from the CPU (e.g., the wager in the present example). As another example, the CPU further, in accord with the execution of the instructions relating to the wagering game, causes the
primary display 12, other display device, or other output device (e.g., speakers, lights, communication device, etc.) to change from a first state to at least a second state, wherein the second state of the primary display comprises a visual representation of the physical player input (e.g., an acknowledgement to a player), information relating to the physical player input (e.g., an indication of the wager amount), a game sequence, an outcome of the game sequence, or any combination thereof, wherein the game sequence in accord with the present concepts comprises acts described herein. The aforementioned executing of computer instructions relating to the wagering game is further conducted in accord with a random outcome (e.g., determined by a RNG) that is used by the CPU to determine the outcome of the game sequence, using a game logic for determining the outcome based on the randomly generated number. In at least some aspects, the CPU is configured to determine an outcome of the game sequence at least partially in response to the random parameter. - Referring now to
FIGS. 4A-4C , awagering game screen 100 is shown. Thewagering game screen 100 includes amain array 102 and three enhanced arrays 104 a-104 c. Themain array 102 includes a plurality of main-array reels 106 a-106 e. A firstenhanced array 104 a includes a plurality of first-enhanced-array reels 108 a-108 e. Similarly, a secondenhanced array 104 b includes a plurality of second-enhanced-array reels 110 a-110 e and a thirdenhanced array 104 c includes a plurality of third-enhanced-array reels 112 a-112 e. Themain array 102 may be presented in either a base game or a bonus event of the wagering game. Similarly, the enhanced arrays 104 a-104 c may be displayed with themain array 102 or as a separate bonus feature. The enhanced arrays 104 a-104 c are locked until a triggering condition is met. - Referring now to
FIG. 4A , each of the enhanced arrays 104 a-104 c is visually associated with a respective enhanced-array trigger symbol 114 a-114 c when locked. Additionally, this display informs the player of the particular enhanced-array trigger symbol 114 a-114 c required to unlock the particular enhanced array 104 a-104 c. When locked, the enhanced arrays 104 a-104 c are not eligible to provide an award to a player in response to a winning combination. It is contemplated that other methods may be used to signify when an enhanced array is not currently in play. - Each enhanced array 104 a-104 c also includes at least one enhancement feature 116 a-116 c associated with it. As will be described in detail in connection with
FIG. 4B , the firstenhanced array 104 a is associated with a “wild reels” enhancement feature 116 a. As will be described in connection withFIG. 4C , the secondenhanced array 104 b is associated with a “random wilds”enhancement feature 116 b and the thirdenhanced array 104 c is associated with a “reduced symbol set”enhancement feature 116 c. It is contemplated that other enhancement features may be used such as free spins, an increased number of bonus event trigger symbols, respins, additional paylines, clumped symbols, locking symbols, loaded reels, etc. Additionally, multiple enhancements may be used on any of the three enhanced arrays 104 a-104 c and/or the enhanced arrays 104 a-104 c may share some enhancement features. - Referring now to
FIG. 4B , themain array 102 is shown displaying a triggering condition to unlock an enhanced array. In this embodiment, the triggering condition is any enhanced-array trigger symbol 114 a-114 d being displayed on the rightmost main-array reel 106 e. The enhanced-array trigger symbol 114 a-114 d “unlocks” the particular enhanced array 104 a-104 c or particular enhanced arrays associated with it. After the wagering game outcome is determined and a first-enhanced-array trigger symbol 114 a is displayed, the firstenhanced array 104 a (i.e., the enhanced array associated withtrigger symbol 114 a) is unlocked and the display of the firstenhanced array 104 a is altered. The illustrated “wild reels” enhancement feature 116 a (FIG. 4A ) is utilized in the firstenhanced array 104 a by the gaming system. The gaming system selects a random number of the first-enhanced-array reels 108 a-108 e to be replaced with wild reels. In the illustrated embodiment, the number of reels to be replaced ranges from two to four. The gaming system then selects the positions of the first-enhanced-array reels 108 a-108 e to be replaced with the wild reels. In the illustrated embodiment, theCPU 30 has randomly selected the three rightmost first-enhanced-array reels 108 c-108 e to be replaced by wild reels. In some embodiments, the selected wild reels are locked in place while the remaining two leftmost first-enhanced-array reels array reels array reels 108 c-108 d. - Referring now to
FIG. 4C , a multiple-enhanced-array trigger symbol 114 d is displayed on thefifth reel 106 e of themain array 102 and is associated with all three enhanced arrays 104 a-104 c. It is contemplated that additional combinations of enhanced-array trigger symbols 114 a-114 d may be included that are associated with more than one, but less than all, of the enhanced arrays 104 a-104 b. As described above, the “wild reels” enhancement feature 116 a (FIG. 4A ) is applied to the firstenhanced array 104 a. In this illustration, the second first-enhanced-array reel 108 b and the rightmost first-enhanced-array reel 108 e were selected to be wild reels using the method stated above. - The “random wilds”
enhancement feature 116 b (FIG. 4A ) is applied to the secondenhanced array 104 b when the secondenhanced array 104 b is unlocked. The illustrated “random wilds”enhancement feature 116 b (FIG. 4A ) is applied to the secondenhanced array 104 b by the gaming system. The gaming system selects a random number of symbols to be replaced on the secondenhanced array 104 b. In the illustrated embodiment, the number of symbols to be replaced ranges from two to five. The gaming system selects the positions of the symbols to be replaced on second-enhanced-array reels 110 a-110 e to be replaced by wild symbols. In the illustrated embodiment, theCPU 30 has randomly selected three array positions to be replaced with wild symbols. These array positions are located at the top of the second second-enhanced-array reel 110 b, as well as the top and bottom of the rightmost second-enhanced-array reel 110 e. In some embodiments, the selected wild symbols are locked in place on the secondenhanced array 104 b while the second-enhanced-array reels 110 a-110 e are spun. A game outcome is then determined based on the locked wild symbols and on the randomly selected symbols displayed on the remaining positions of the secondenhanced array 104 b. - The illustrated “reduced symbol set”
enhancement feature 116 c (FIG. 4A ) is applied to the thirdenhanced array 104 c by the gaming system after the thirdenhanced array 104 c is unlocked. In the illustrated embodiment, the “reduced symbol set”enhancement feature 116 c includes a plurality of symbols arranged on the plurality of the third-enhanced-array reels 112 a-112 e of the thirdenhanced array 104 c. The set of symbols on the third-enhanced-array reels 112 a-112 e includes symbols used on themain array 102, but excludes the lowest paying symbols in that set. The number of symbols excluded from the third-enhanced-array reels 112 a-112 e may be varied to achieve a desired result. By way of non-limiting example, the set of excluded symbols can be a predetermined set or can be randomly determined by the gaming system during play of the wagering game. -
FIG. 5 illustrates a schematic depiction of one algorithm that corresponds to at least some instructions that can be executed by theCPU 30 and/orexternal systems 48 to perform the above described functions associated with the disclosed concepts. By way of non-limiting example, theexemplary algorithm 200 includes receiving a wager, atstep 202, from a player to initiate a wagering game. The wager is placed or otherwise confirmed, for example, using abill validator 22, coin acceptor,information reader 24, or other input device. A main array and enhanced arrays are displayed at step 204 (e.g., themain array 102 and enhanced arrays 104 a-104 c ofFIG. 4A ). It is contemplated that the main array and the enhanced arrays can also be displayed prior to initiation of the wagering game. - After receiving the wager from the player, a game outcome is generated. In the illustrated embodiment, the main array includes a plurality of symbol-bearing reels that are spun and evaluated at step 206 (e.g., the main-array reels 106 a-106 e of
FIGS. 4A-4C ). It is determined, atdecision box 208, whether a triggering condition has occurred that enables play of any enhanced arrays (e.g., as shown inFIG. 4B , the first-enhanced-array trigger symbol 114 a being displayed on the rightmost main-array reel 106 e allows play of the firstenhanced array 104 a). If a triggering condition has not occurred, an award determination is made atstep 212 to evaluate whether the main array resulted in an award to the player. Alternatively, if a triggering condition has occurred, at least one enhanced array associated with the triggering condition is unlocked and the symbol-bearing reels on the unlocked enhanced array are spun and evaluated atstep 210. - In the illustrated embodiment, the unlocked enhanced array includes a plurality of symbol-bearing reels (e.g., the first-enhanced-array reels 108 a-108 e shown in
FIG. 4B ). It is contemplated that multiple triggering conditions may occur simultaneously and that either all or fewer than all enhanced arrays associated with the triggering conditions may be played. It is further contemplated that multiple enhanced arrays may be associated with a single trigger symbol (e.g., the multiple-enhanced-array trigger symbol 114 d shown inFIG. 4C ). After the enhanced array has been spun and evaluated atstep 210, an award determination is made atstep 212 to evaluate whether the main array, enhanced array, both, or neither resulted in an award to the player. These awards are based on, for example, combinations of symbols displayed on the main array and symbols displayed on any unlocked array. The player is provided with any determined awards atstep 214 and play of the wagering game may continue. - In some embodiments, play of the unlocked enhanced arrays can unlock other of the enhanced arrays or cause the main array to respin. For example, play of the first
enhanced array 104 a can result in displaying a second-enhanced-array trigger symbol 114 b that unlocks the secondenhanced array 104 b. Or, in another example, play of the firstenhanced array 104 a can result in a respin symbol that causes themain array 102 to respin one or more times. Furthermore, the respinning of themain array 102 can potentially unlock other enhanced arrays, for example, a third-enhanced-array trigger symbol 114 c unlocks the thirdenhanced array 104 c. - In some embodiments, the number of enhanced-array trigger symbols 114 a-114 d increases if a free-spin bonus game is triggered on the
main array 102. In this embodiment, the plurality of main-array reels 106 a-106 e includes only three enhanced-array trigger symbols 114 a-114 c during the base game, each of the enhanced-array trigger symbols 114 a-114 c being able to unlock a single and distinct one of the enhanced arrays 104 a-104 c. When a free-spin bonus is initiated, as indicated by an information area 118 (FIG. 4C ), the multiple-enhanced-array trigger symbol 114 d is added to the plurality of symbol positions on at least one of the main-array reels 106 a-106 e. The multiple-enhanced-array trigger symbol 114 d is able to unlock all three enhanced arrays 104 a-104 c simultaneously. Alternatively, during a free-spin bonus game, all of the single, enhanced-array trigger symbols 114 a-114 c convert to multiple-enhanced-array trigger symbols 114 d. - In yet other embodiments, the number of enhanced-array trigger symbols 114 a-114 d does not change when the free-spin bonus is initiated. In this embodiment, an enhanced array that becomes unlocked due to a triggering condition remains unlocked and is spun and evaluated for the remainder of the free spins. For example, if the free-spin bonus has ten free spins and the first
enhanced array 104 a is unlocked during the third free spin, the firstenhanced array 104 a remains unlocked and is spun and evaluated for each of the remaining seven spins (in addition to the third spin). - While the present devices have been described using a single-symbol trigger on the rightmost main-
array reel 106 e, it is contemplated that a single-symbol trigger may be implemented on any of the main-array reels 106 a-106 e. In alternative embodiments, a combination of symbols or a specific placement of symbols may be required to unlock the enhanced arrays. This requirement can include a trigger with three symbols where all three symbols indicate the enhanced array to be unlocked. For example, in reference toFIG. 4B , two additional first-enhanced-array trigger symbols 114 a would be required to be displayed on any of the main-array reels 106 a-106 e. Alternatively, the three first-enhanced-array trigger symbols 114 a could be required to be located in a specific location or orientation (e.g., all three symbols must be located in a top position on any of the main-array reels 106 a-106 e of the main array 102). In yet another alternative, the three symbols could be different from one another (e.g., one symbol identifies the enhanced array to be unlocked and the other two symbols are generic bonus symbols). - Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims.
